Hi,
Maybe this will work, go to settings, at the bottom you see about the phone, click on that and at the bottom you must see the certification number, thats your reg code.
It works with my pad and I hope for you too.

Where can I find instructions on updating our a1cs X220, I had to flash it when it crashed but now we can't register it as we haven't got a copy of the key and the supplier hasn't got a copy.
Can we update to a version that does not need a key?
